Does Addition of Adductor Canal Blockade to Multimodal Periarticular Analgesia Improve Discharge Status, Pain Levels, Opioid Use, and Length of Stay after Total Knee Arthroplasty?

Total knee arthroplasty (TKA) can be associated with substantial postoperative pain that may affect satisfaction and return to function. Various forms of pain control have been used; however, multimodal periarticular analgesia (MPA) and adductor canal block (ACB) have recently gained popularity. The purpose of this study was to compare (1) discharge status, (2) pain levels, (3) postoperative opioid consumption, and (4) length of stay (LOS) between TKA patients who received MPA only and those who received both MPA and ACB.
